Tenacity Herbicide is only labeled for use on St. Augustine grass that is grown on sod farms. It cannot be used on St. Augustine in residential lawns. Blindside WDG Herbicide is labeled to treat crabgrass in residential St. Augustine lawns.
Tenacity Herbicide is only for use on St Augustine when used in sod farm and cannot be used on home lawns that have St Augustine.
Tenacity Herbicide would be mixed at the same rates listed on the label on your turfgrass for using solo when tank mixing with Barricade. You would only used reduced rates if mixing with atrazine, bentazon or simazine.
Tenacity Herbicide only lists on the label that seashore paspalum is sensitive to it. It is not however labeled for use on St Augustine lawns so would not be recommended. It can only be used on St Augustine grown for sod.
The label for Poa Constrictor does not mention anything about tank mixing with another herbicide such as Tenacity Herbicide. Per the Tenacity label: Other tank mixture partners may be safe but have not been tested. Turf managers wanting to tank mix Tenacity with other herbicides should test on a small basis for compatibility, safety and efficacy before treating large areas.
We would recommend doing a compatibility test before treating.
Your timing is really going to depend on a lot of factors, such as the weeds you are targeting and if/when you are seeding. We would exercise caution if you are applying multiple herbicides at the same time, especially since Trimec is already a blend of 3 active ingredients. Mixing Trimec and Tenacity would be used only as a spot spray, and we would still do a small jar test before mixing a tank of these as well as testing an inconspicuous area of the lawn for tolerance first. You should only use Tenacity as a broadcast pre-emergent application if you are renovating or overseeding the lawn, and most Trimec products require you to wait 2-4 weeks after application before you can reseed. Please let us know if you have additional questions about your application.
Tenacity Herbicide should not be sprayed on edible crops, including almond trees. The product should be applied outside of the dripline of the trees, and take special care not to allow any overspray or drift to contact the tree.
Tenacity Herbicide is only labeled for use on turfgrasses. It could harm ornamental grasses if applied over them.
As long as you are not spraying the roses directly, you can use Tenacity Herbicide on the grass below.
Tenacity is labeled for control of yellow nutsedge only. Tenacity does not cover other species of nutsedge. We do carry Sedgehammer which is labeled for all species of nutsedge.
We would recommend contacting the airline directly for restrictions on transporting Tenacity Herbicide in the air.
Tenacity Herbicide is not labeled to prevent or eradicate lespedeza.
Tenacity Herbicide reapplication times can vary depending on the target weed and application. Please refer to the product label for complete information.
As long as you are not applying either product during the heat of the day, you can use SpeedZone the same day as Tenacity Herbicide. Just allow areas to dry between treatments
Tenacity Herbicide is not labeled to be applied in or around edible vegetation. When applying the product to your lawn, you would want to be sure to avoid over-spray or drift of spray applications onto the fruit trees, and avoid spraying within the drip line of any edible trees.
While you could potentially do a split application with Tenacity for a fall pre-emergent, usually you would wait at least 6-8 weeks between applications in that case. Keep in mind that the annual maximum application rate for Tenacity is 16 oz per Acre per year (used in 12 months), so you want to be careful you are not exceeding that rate. Be sure, too, that you are not exceeding the application rates for your type of turfgrass.
Tenacity Herbicide only states that it can cause undesired injury to kikuyugrass but it does not give instructions on how to control with Tenacity, which leads us to believe it may only temporarily damage it rather than actually kill it all the way out. Once your new seed has come up and become established to tolerate herbicide use, you could use Hi Yield Turflon Ester to spray over the kikuyugrass to eliminate it from the ryegrass in the lawn.
Per the Hi Yield Turflon Ester Product Label for Control of Kikuyugrass:
Apply Hi-Yield Triclopyr Ester at a rate of 3/8 to 3/4 fluid ounces per 1000 square feet. To improve activity, MSMA herbicide may be tank mixed with the ½ quart per acre rate of Hi-Yield Triclopyr Ester. Three to four additional applications at 4 to 6 week intervals may be required to achieve control of kikuyugrass
Tenacity Herbicide not labeled for zoysiagrass and would not be recommended to apply to it at all.
We don't recommend using Tenacity Herbicide to get rid of weeds in ornamental plants, it's not labeled for this use. If you have broadleaf weeds, you will need to spot treat with a non-selective herbicide. If you have grassy weeds, you can use a product like the Bonide Grass Beater around listed ornamentals on the label.
Foliage of treated weeds will cease growth after Tenacity Herbicide application, then turn white (loss of chlorophyll) and death may take up to three weeks. A repeat application is required after two to three weeks for improved postemergence weed control.
